I am making a module for a plugin. The main application loads the plugin, which then loads the modules for my plugin (Main Application --Loads Plugins--> My Plugin --Loads Modules--> My Module).
I have a jar (we'll call it dynamicJar) that I am loading dynamically into my plugin. The issue I have is when I want to use methods and classes from my plugin in dynamicJar I get a NoClassDefFound error:

The issue is that I CAN run methods from the Main Application inside of the dynamicJar, but I can't use the methods from the plugin inside of the dynamicJar.
TL;DR: Using classes that are from the plugin jar throws a ClassNotFoundException and NoClassDefFoundError when they are used from a dynamically loaded jar.
EDIT:
Here is the code I am using to load the jars into my class path.
Method method = URLClassLoader.class.getDeclaredMethod("addURL", new Class[]{URL.class});
method.setAccessible(true);
method.invoke(ClassLoader.getSystemClassLoader(), new Object[]{file.toURI().toURL()});
I solved the issue by loading the classes into the class loader of the plugin, instead of it's own class loader or the System class loader. Works flawlessly now.

I am new to work on Geoserver,now i have a requirement to run geoserver over https. I had followed some steps to configure jetty for https but it didn't work,i might have went wrong somewhere.

These are the errors(ref image).
I am not so good in java too.
Don't run the platform independent binary in production!
If you still need to add HTTPS support then you need to follow the Eclipse instructions to add HTTPS to Jetty.
Without knowing how far you got along that path it's impossible to give any further advice.
I have created one ICF based Flat file connector which uses REST web service to Read/write the data from file. I have used jersey implementation 1.6 to write the web service and the java client which will call that web service.
I am using stand alone java code for testing the CRUD functionality.It's giving exception at first line where I am initializing the jersey Client.
Client flatFileRestClient = Client.create();
I got to know that the error is because the connector server is not able to recognize the jersey implementation jars.So as per documentation of ICF connector i had put the jersey bundle jar in connector server/lib folder. I had restarted the connector server and invoke create operation but issue still exists.
I had also added the class path of custom jar in ConnectorServer.bat
file located in CONNECTOR_SERVER_HOME/bin. Still the issue persists.
Please find full stack trace of the exception thrown on eclipse console:

Any help at the earliest would appreciate.
The problem was due to the REST API jars which i was using. I have de-compile the jersey-bundle-1.6.jar and found the javax.ws.rs.ext.Providers.class is not present in that jar. So i have downloaded the Java 6 complied version of the Jersey-bundler-1.16.jar
I am getting the following error:

Exception running application StartUp
However i am not even using the Hibernate library, i am using JPA, i tried searching for "Session", "hibernate" and other strings but i can't find any of those and yet it is throwing this error.
These are the libraries i am currently using:
I was using hibernate before but i had to use JPA, so i removed everything that had to do with Hibernate.
The stacktrace is referencing to some of my files but nothing on those lines has anything to do with database management.
Have you added Hibernate JAR's to the lib directory of your server by any chance?
Well the stack trace says clear enough that "gui.GraphicApplication.(GraphicApplication.java:28)" is referencing it, so look at that and fix it?
I'm trying to debug a web app in IntelliJ Idea, which is deployed to a local Tomcat 6 server in form of an exploded WAR.
At the start of the application I get ClassNotFoundExceptions, even though the exploded WAR directory contains those classes (in its WEB-INF/classe subdirectory).
When I launch the web app in IntelliJ Idea (press the Debug 'Tomcat' button) and look into the Tomcat webapp directory (C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps), I don't see there a directory with my exploded WAR.
Therefore, I think that the exploded WAR is not copied to the respective Tomcat directory.
How can I fix this (make sure that Tomcat sees all class files from my exploded WAR directory) ?
Update 1 (18.09.2013 13:46 MSK):
Here's the stack trace:

I have a similar app which happens to be a maven project, and by default it uses the target (output) directory. However this can be verified by:
Look for the following line in the startup log Using CATALINA_BASE: "C:\Users\xxxxx\.IntelliJIdea12\system\tomcat\Unnamed_bpt_5"
Go into the directory specified in the log message, then into conf\Catalina\localhost
Open the xml from the folder and check the docBase
Also, please ensure that on the Run/Debug configuration page in the Before launch section you have added Make (or maven package) goal so it will compile your classes and resources
I'm trying to read a scala object(the type is Seq[(Seq[DenseMatrix[Double]], DenseMatrix[Double])]) from a file, I have the classes in my classpath, but I still get a mysterious ClassNotFoundException. DenseMatrix is specialized for Double, could that be the problem?
Here is the stack trace:

I've had the same problem. I solved it by putting the class files inside the libs folder that in the project folder and then add them to the classpath again.
